Biofilm formation during ultrafiltration membrane operation was investigated by Compressed Sensing Magnetic Resonance Imaging (MRI), with tryptic soy broth included in the feed stream to stimulate microbial growth. Biofilm development was visualized as growing layer characterized by reducedT1relaxation time, and its progression as monitored by MRI was compared with classical integral filtration parameters such as permeate fluxJ, transmembrane pressure Δpand permeabilityLpto document fouling behavior. Over three days of growth a change in the filtration process could be observed in both measurements, withLpdecreasing dramatically over time as the surface-associated biofilm increased in thickness. Following cessation of filtration and the associated drop in Δp, the biofilm detached from the lumen wall and dispersed throughout the feed channel. Compressed Sensing MRI velocity and intensity measurements facilitate fast imaging during filtration processes, providing new possibilities for the investigation of biofouling in filtration membranes.
